London: Singer Rihanna, who was assaulted by her ex-boyfriend Chris Brown, says she needed a "wake-up call" from god to make her realise their relationship was over.

"God has a crazy way of working, and sometimes when stuff happens you feel like, `What did I do to deserve this?` Why was it backfiring on me?" femalefirst.co.uk quoted her as saying.

"But I needed that wake-up call in my life. I needed a turning point, and that`s what god was giving to me," she said.

Rihanna, who is now dating baseball star Matt Kemp, admits it wasn`t easy to end her three-year relationship with the "Run It" singer, but is happier now since he is no longer in her life.

"I remember I was in New York at the Trump Hotel and I woke up and I just knew I was over it. It was a different day. I felt different. I didn`t feel lonely. I felt like I wanted to get up and be in the world. That was a great, great feeling," she said.
